Changed my mind about spray foam insulation after helping my brother in his attic in Austin last July.
I always thought the DIY foam kits were a scam, too expensive for what they do. But my brother was redoing his 1920s bungalow in Austin and talked me into helping him foam his attic. It was 104 degrees outside and we were up there sweating, and he had this infrared thermometer. Before we sealed anything, the attic temp was like 135 degrees. After we sprayed the rakes and between the joists, it dropped to under 100 in about an hour. That convinced me. The air seal is way better than fiberglass because it fills every tiny crack. I still think the cleanup is a nightmare though, sticky foam gets everywhere. Has anyone else had good luck with the tiger claw foam guns or are the disposable cans fine for a small garage job?
